From section 8 of the NCAA rulebook (page 62):
Contact to the Head
SECTION 8. A player shall not make contact with an opposing player’s
head or neck area in any manner.
PENALTY—Minor or major or disqualification at the discretion of the
referee. Contact to the head shall be assessed in front of the
infraction (i.e., contact to the head – elbow).
Note: The rules committee instructs officials to use a zero tolerance policy in
Does the rule actually eliminate head shots? No. At the OSU vs. MSU games this weekend, seven out of the 20 penalties involved contact to the head. But the penalty serves to discourage it.
The verbiage and enforcement of this rule in the NCAA could serve as a model for the NHL.
